Fine, how about a function that can be called by pg_dump (and anyone
else who has the rights and feels the need) to set that value?  That
avoids all need for any new syntax and still gives us the pg_dump and
friends support that will apparently be asked for.

There is no case where ALTER should change the *creation* time, imo.

The last psql \d support change that I looked at (thanks Jon) had a
diffstat (excluding documentation and whitespace changes) of:

sfrost(at)beorn:/home/sfrost/Downloads> cat qq | diffstat               
 describe.c |    5 +++++
 1 file changed, 5 insertions(+)

Just saying. ;)
